Observing, Describing, and Identifying Clouds [PDF]

open access: yes, 2003
In this activity students observe and sketch clouds, describing their forms. They initially generate descriptions of a personal nature and then move toward building a more scientific vocabulary.

Radiative Effects of contrails and contrail cirrus

open access: yes, 2015
Contrails and contrail-cirrus contribute a large share to aviation’s greenhouse forcing and strategies to mitigate their adverse effects have been quested after for many years now. The magnitude of radiative forcing due to contrails and contrail-cirrus is yet uncertain and, surprisingly, many years of research and many measurement campaigns could not ...

Simulation and Optimization Methods for Assessing the Impact of Aviation Operations on the Environment [PDF]

open access: yes, 2010
There is increased awareness of anthropogenic factors affecting climate change and urgency to slow the negative impact. Greenhouse gases, oxides of Nitrogen and contrails resulting from aviation affect the climate in different and uncertain ways.

Feasibility of climate-optimized air traffic routing for trans-Atlantic flights [PDF]

open access: yes, 2016
Current air traffic routing is motivated by minimizing economic costs, such as fuel use. In addition to the climate impact of CO2 emissions from this fuel use, aviation contributes to climate change through non-CO2 impacts, such as changes in ...

The Use of Meteorlogical Data to Improve Contrail Detection in Thermal Imagery over Ireland. [PDF]

open access: yes, 2009
Aircraft induced contrails have been found to have a net warming influence on the climate system, with strong regional dependence. Persistent linear contrails are detectable in 1 Km thermal imagery and, using an automated Contrail Detection Algorithm ...

The dependence of contrail formation on the weather pattern and altitude in the North Atlantic [PDF]

open access: yes, 2012
Aircraft flying through cold ice-supersaturated air produce persistent contrails which contribute to the climate impact of aviation. Here, we demonstrate the importance of the weather situation, together with the route and altitude of the aircraft ...

High-resolution modeling of early contrail evolution from hydrogen-powered aircraft [PDF]

open access: yesAtmospheric Chemistry and Physics
In this study, we investigate the properties of young contrails formed behind hydrogen-powered aircraft, particularly compared to contrails from conventional kerosene combustion. High-resolution simulations of individual contrails are performed using the

Properties of individual contrails: A compilation of observations and some comparisons

open access: yes, 2016
. Mean properties of individual contrails are characterized for a wide range of jet aircraft as a function of age during their life cycle from seconds to 11.5 h (7.4–18.7 km altitude, −88 to −31 °C ambient temperature), based on a compilation of about ...

Real-Time Contrail Monitoring and Mitigation Using CubeSat Constellations

open access: yesAtmosphere
Contrails, or condensation trails, left by aircraft, significantly contribute to global warming by trapping heat in the Earth’s atmosphere. Despite their critical role in climate dynamics, the environmental impact of contrails remains underexplored. This
